DRAWBAR FR- HAELROVVS.

Application filed July 30, 1924.

This invention relates to av drag-bar for use in connect-ion withharrows. 1n the work of farming it has been the lcustom to use a numberof harrows and to use a single draw-bar ot considerable length to whichthe harrows are attached, said harrows while thus attached beingdisposed side by side'to be drawn across a ield, the advantage, in part,being that, within a certain limit of time, a greater area of ground maybe harrowed than ordinary, and thatrun-dulating or rough surfaces may beadequately harrowed. c Y

However, in' instances when it is necessary to drive upon a highway, orwhen moving through a gateway, or when it is desired to move the harrowsbetweenobstructions, it has been found that the drag-bars heretoforeused operate to great disadvantage on account of their required length.

The invention has for its object to provide a drag-bar having removableend-extensions, `each extension being adapted to co-operate with thedrag-bar for supporting a harrow, and adapted to be readily removed topermit the harrows to be laid one upon another to occupy a limited areaat the rear of the main drag-bar, so that the harrows may be moved upona ,comparatively narrow high- 30 way or through a gateway or through anarnow passageway between obstructions.

With the foregoing objects in view and others vto be mentionedhereinafter the invention presents a novel and useful construction,combination and arrangement of parts, as described herein and claimed,and kas illustrated in the accompanying drawing, it being understoodthat changes in form, size, proportion and minor details may be made asfound to be of advantage, said changes being determined by the scope o tthe invention as claimed.

In the drawing, Fig. 1 is a plan view showing the harrows disposed oneupon another, the 'end-extensions being removed from the main drag-bar,and not shown. Fig. 2 is a plan view` showing harrows connected with thedrag-bar and its extensions.- Fig. 3 isa view in longitudinal section cithe drag-bar and its extensions. el shows one of the bar-extensions, itstubular part being in longitudinal section.

Referring now to the drawing for a more particular description, numeral5 indicates a drag-bar provided at its ends with suitable holdersorU-clips 6 which project for- Serial No. 729,978.

wardly, and to which may be attached a connecting-bar 7 for supportingthe whiiiletrees S so that the harrows, indicated at 9, 10 aml 1 1 maybe drawn, said drag-bar 5 being provided with suitable holders orU-clips 12, 13, lll vand 15 which vextend rearwardly therefrom, chains16 or other suitable holder elements being employed which connect theharrows with the rearwardly projecting clips mentioned.

F or purposes ot the invention we provide removable extensions 17 and18iior the dragbar 5, the extension 17 being provided at its outer endvwith a holder or U-clip 19 and the extension 18 being also provided atits outer end with a sin'iilar U-clip 20. Numeral 2l indicates a chainwhich may be used for connecting the U-clip 19 with the harrow 9 andwhich may be removed therefrom, and numeral 22 indicates a chain whichmay be used Yfor connecting the U- clip 20 with the harrow 11 and whichmay be removed therefrom.

Ti/Jhile chains have been specifically mentioned and are preferred, anyother suitable means may be substituted if desired for removablyconnecting the outer ends of the extcnsionsl and 18 with the respectiveharrows 9 and 11.

For further purposes of the invention the main drag-bar 5, andextensions 17 and 1S are of tubular form, each extension being providedwith a projection or arm 23 which extends out Jtrom its inner end for aslidable mounting in the outer end of the tubular drag-bar 5. Numerals24 indicate keepers or set-screws for securing the arms 23 in stationaryrelation with the tubular extensions 17 and 18.

Having thus described the several parts, operation will be readilyunderstood. 1ifvhile in use for harrowing, the drag-bar 5 and itsextensions 17 and 18, together with the harrows, are disposed as shownin Fig. 2 of the drawing, the chains 21 and 22, which are connected withthe outer ends of the respective extensions 19 and 20, operating tosnpport the harrows 9 and 11.

When it is desiredto more from one field to another, or to move uponV anarrow highway or to cross narrow bridges, and especially when it isdesired to move through a gateway, the chains 21 and 22 are unfastenedand the extensions 17 and 18 are reharrows 9 and 11' may then be swungto lie upon the harrow 107 so that the harrows will occupy a limitedarea to permit a movement through an ordinary gateway or othercomparatively narrow passageway.

It will be seen that while the ldevice is in use, the extensions 17 and1S, although slidingly disposed within. will not slide outwardly tromthe tubular drag-bar 5, but, normally, will remain in the positionsshown in Fig. 2 of the drawings. Also it will be noted that while theprojections are disposed in the tubular draw-bar 5, an end ot achextension operates as a stop-member to limit a movement in one directionot an e5:- tension.' rEhe diameters ot the tubular bar and theextensions 17 and 18 are practically uniform. and as is obvious, an endot an extension in engagement with an end ot said tubular bar will tendto resist stresses directed to said extension by a harrow.

Among some ot the advantages to be dcrived by use ot the invention asdeseribeth it may be stated that the drag-bar includiio' its extensionsconsists oi 'tew simple pax and may be manufactured at a limited er;-pense; it may have any required length 'tor supporting harrows havingadequate widths. and the extensions may be conveniently removed from themain drag-bar 5 for the purposes mentioned, and may be readily replaced.

It will be understood that while movin;Y through narrow gateways or thelile, the chains 1G tor the harrow 10 will be supot the har .3, andsince the extensionsy 17 and 18 should normally be disposed in alignmentwith the bar 5, they should be constructed oit material adapted tosustain stresses directed thereto.

Ve claim as our invention,-

In a drag-bar tor supporting a harrow and secondary harrows, a tubularbar connected with a single harrow and havingA holder-elements at itsends lor connections with the secondary harrows, and a pair of secondarybars each provided with a stop member, a projection and aholder-clement, each secondary bar being adapted to he disposed with itsstop-member in engagement with an end ot the tubular bar with itsprojection slidinfg'ly disposed therein tor a removable connection otits liolderele1nent with a secondary harrow.

ln testimony whereof. we have atiixed our signatures.
